Accuracy when opening DXF files
Opened a DXF file in Draftsight to confirm size. When opened in Illustrator 2026, the size is not accurate. When opened in 2024 and 2025, the size is correct. Tested on different computers and the results are the same. What should be .044 inches in size shows up as .0474, which is not acceptable. Opening in Affinity Designer2 or Corel, the sizes are correct. Working with a part that is only .414 in diameter, any inaccuracy is unacceptable. Original DXF file was created in inches and I have tried all possible options to achieve the correct sizing in version 2026 without any success. Opening and placing produce identical results. Scaling is not an option, as the results produce closer values, they too are not exact due to the percentage factor limitation.
Bottom line, newest version or Illustrator is inaccurate and any other program that can handle DXF files works just fine. Fortunately I discovered the error after producing 3 new parts. Never had issues and I failed to verify the size of the DXF import. Have used the same procedure for perhaps 750 designs like this and never thought something like this could happen.
